tap: Check return value of accept4() before calling getsockopt()
Reported by Coverity (CWE-119): Negative value used as argument to a function expecting a positive value (for example, size of buffer or allocation) and harmless, because getsockopt() would return -EBADF if the socket is -1, so we wouldn't print anything. Check if accept4() returns a valid socket before calling getsockopt() on it. Signed-off-by: Stefano Brivio <sbrivio@redhat.com> Reviewed-by: David Gibson <david@gibson.dropbear.id.au>
